Abstract: As a pillar industry of the global economy, the construction sector faces severe environmental challenges while driving development, with massive amounts of construction waste generated annually exerting significant pressure on the ecological environment. Building Information Modeling (BIM) technology, leveraging its advantages in digitization, visualization, and collaboration, provides an innovative pathway for the whole-life cycle management of construction and demolition waste(CDW). Based on an analysis of the current status of CDW, this paper systematically reviews the core applications of BIM technology in waste prediction, management, and circular utilization. By integrating with the Industry 4.0 technology framework, it proposes optimized management strategies for CDW based on BIM and validates their effectiveness through empirical cases. The study demonstrates that BIM technology significantly enhances waste management efficiency, promotes the green and low-carbon transformation of the construction industry, and provides technical support for achieving circular economy goals.
